COLLECTOR FOR FUEL CELL AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To provide a collector for a fuel cell capable of enlarging a contact area with an electrode without reducing the volume of a gas passage. SOLUTION: This collector for a fuel cell is electrically conducting to an electrode 12 by forcing it into contact with the electrode 12 provided on the surface of a solid electrolyte 11, and a gas passage 13 is partitioned and molded between it and the surface of the electrode 12. Many protruding parts 15 toward the electrode 12 in order to contact the electrode 12 is formed on a plate surface part 14 facing the surface of the electrode 12, and a swelling part 16 swelling in a direction along the surface of the electrode 12 is formed at the top part of the protruding part 15 to contact the electrode 12.
